Matt Sherratt was left bitterly disappointed after Cardiff fell to an agonising last-gasp defeat to Ulster on Friday night.
Cardiff looked to have sealed a well deserved win when Theo Cabango raced clear for what would have been a hat-trick in the 77th minute.
But following a TMO intervention the try was controversially scratched off and Ulster kicked the ensuing penalty to snatch a narrow win.
To compound Cardiff’s woes an early Ulster try was awarded despite what appeared a knock on in the build up and the ball was kicked from Thomas Youngs arm in the act of scoring.
Sherratt said: “It's hard to look past the last 90 seconds, isn't it? So probably thoughts on that period. I thought it was a pretty cruel way to end a game.
“I don’t really want to talk about the decision too much because I'd like to have a look back at it. Is it clear and obvious enough to chalk a try-off and it decide a game?
“But that's a referee's choice. All we can do when the dust settles is have a look back and figure out why it went to the last minute because I thought there’s some games you could have won and that's probably one we should have won. We had chances to win.
“But I think in this game there were some big decisions that went against us. Their try there’s clearly a knock on at the line out. I can see Mike Adamson has got us back to that, it's fair enough. But there's a linesman, a touch judge, stood five metres away.
“At this level that's not that's not good enough, those are the calls you've got to get right. We've had the ball kicked out of our hands over the line by Thomas Young and then a real cruel decision at the end.
“As I said at the moment it's hard for me for me to look past that but we will look past it though. We’ll look at what we can do to get better. I know what that is anyway, we need to put more pressure on the opposition around the halfway line to get more 22 entries.”
